On the other hand, the supply unit 120 communicating with the bottom surface of the tension providing unit 110 is provided with a third valve 122 that blocks the flow of air according to rotation in order to control the flow of air. It is possible to adjust the amount of air moved to (110).

As described above, the elastic culturing part 130 is inserted into the tension providing part 110 , and the sidewall of the elastic culturing part 130 is inserted into the gap between the outer wall 112 and the inner wall 114 . The inner wall 114 and the elastic culture unit 130 form a closed space in the inner space, and the side wall of the elastic culture unit 130 is in close contact with the outer wall 112 and the inner wall 114 and fixed can be

Here, the substrate member to prevent the cells (C) from being damaged while the cells (C) positioned on the elastic culture unit 130 are in close contact with the elastic culture unit 130 and the compression unit 140 . A 142 may be provided between the elastic culture unit 130 and the compression unit 140 .

At this time, the substrate member 142 may be formed of a sponge material or a gel-like material to prevent the cells (C) from being damaged, but it is not toxic to the cells (C), and the A material in which micropores are formed so that the medium can be moved through the circulation unit 220 may be more efficient.

For example, the matrix member 142 is not toxic to the cell (C), and since micropores must be formed so that the medium can be moved, an environment similar to the extracellular matrix of the cell (C) can be created. No toxicity acts on the cell (C) using alginate, a material that can environment can be created.

As described above, when air is moved through the supply unit 120 into the enclosed space formed by the elastic culture unit 130 and the inner wall 114, the upper portion of the elastic culture unit 130 is the tension providing unit ( 110) is expanded in a hemispherical shape toward the upper portion, and the compression unit 140 may be deformed toward the upper portion of the tension providing unit 110 as the elastic culture unit 130 expands.

At this time, as shown in FIG. 4 , in order to deform the compression part 140 into a hemispherical shape toward the upper portion of the tension providing part 110 so that the compression part 140 corresponds to the elastic culture part 130 , the support part 150 is the It may be inserted into the compression unit 140 to support the inner edge of the compression unit 140 .

Based on the above-described configuration, the function may be described in more detail with reference to FIGS. 5 to 8 .

Specifically, FIG. 5 is a view showing a situation in which air is injected inside the elastic culture unit of a culture device and a culture system that provides an environment similar to a human body including a cell culture unit according to an embodiment of the present invention, FIG. 6 is 7 is a view showing a situation in which a compressive force is applied to cells of a culture apparatus and a culture system that provide an environment similar to a human body including a cell culture unit according to an embodiment of the present invention. 8 is a diagram showing a situation in which a culture device and a culture system providing an environment similar to the human body including the cell culture unit are moved and FIG. 8 is an environment similar to the human body including the cell culture unit according to an embodiment of the present invention It is a view showing a situation in which the culture equipment and culture system that provide the medium are moved as viewed from the top.

First, as shown in FIG. 5 , when air is injected into the closed space formed by the elastic culture unit 130 and the inner wall 114 through the supply unit 120 , the elastic culture unit 130 that can be stretched is the upper part. It expands toward a hemispherical shape, and tension may be applied while the cells (C) attached to the upper portion of the elastic culture unit 130 are pulled toward the circumference of the elastic culture unit 130 .

As the elastic culture unit 130 expands in this way, tension can be applied while pulling the cells (C) in the circumferential direction of the elastic culture unit 130, and since the cells (C) are pulled in all directions, conventionally There is an effect of creating an environment similar to the internal environment of the human body rather than the tension acting only on both sides of the cell (C).

When the elastic culturing part 130 is expanded upward, the compression part 140 positioned on the elastic culturing part 130 expands the elastic culturing part 130 while the tension providing part 110 . Pressure may be applied to the cell (C) by a force that is deformed upward and returns to a position before deformation.

At this time, since the cells C may be damaged by the pressure applied by the compression unit 140 , the substrate member 142 is disposed between the compression unit 140 and the elastic culture unit 130 as described above. ) may be provided.

Here, as shown in FIG. 7 , the substrate member 142 has micropores formed therein so that the medium and oxygen can move so that the cells C can grow, and the drug injected through the inlet 220 and It can act on the cell (C) together.

In more detail, as shown in FIG. 8 , the medium is moved between the compression unit 140 and the elastic culture unit 130 through the micropores formed in the substrate member 142 and the cells (C) is delivered to, and may be moved toward the discharge unit 240 along the micropores of the substrate member 142 .

Based on the above-mentioned contents, the cell (C) is the tension applied inside the human body as the elastic culture unit 130 expands, the tension is applied, and the compression force is pressurized by the force that the compression unit 140 is restored to. and a compressive force is applied, and an environment similar to the extracellular matrix is created by the matrix member 142, so that it can grow in an environment more similar to that of the human body.

As such, when the drug is injected into the cell (C), if the cell (C) is not subjected to tension and compressive force, since a slight difference may occur in the time and application time of the drug, etc., of the present invention It may be more effective by applying both tension and compression force in the cell culture unit 100 according to an embodiment.

In addition, when the drug is injected into the cell (C), when directly injected into the cell (C), or when the drug is put into the cell (C) and applied, the drug passes through the blood vessel inside the human body Similar to the injection of the drug, since it acts on the cells C through the micropores of the matrix member 142, the effect of the drug in the human body can be confirmed more similarly.

When a plurality of the cell culture units 100 are used to culture the cells C using the cell culture unit 100 described above, there is a space inside so that the cell culture units 100 can be arranged. The housing in which this is formed and the supply unit S in which air is moved toward the cell culture unit 100 may be provided.

Here, the supply unit (S) may be formed as a passage divided to be connected to the bottom surface of each of the plurality of the cell culture units (100), and the supply unit (S) is a plurality of the cell culture units (100), respectively It may be formed to have the same length as

For example, the at least one supply unit (S) connected to the cell culture unit (100) is divided at least once to communicate with the cell culture unit (100), and the divided supply unit (S) is Each length may be the same from the initially divided position to the plurality of cell culture units 100 .

As described above, preferred embodiments according to the present invention have been described, and the fact that the present invention can be embodied in other specific forms without departing from the spirit or scope of the present invention in addition to the above-described embodiments is one of ordinary skill in the art. It is obvious to them.
